The area of the parallelogram is 55 square feet
<h3>How to determine the area of the parallelogram?</h3>
From the figure, we have the following dimensions:
Height = 5 ft
Base = 11 ft
The area of the parallelogram is calculated as:
Area = Base * Height
This gives
Area = 5ft * 11ft
Evaluate the product
Area = 55 square feet
Hence, the area of the parallelogram is 55 square feet

<span>a. find the number of units of tacos she must sell to minimise her cost.
</span>to find a minimum we need to find the function derivative and make it equal to zero:
dc/dx = 2x - 40 = 0
2x = 40
x = 20
therefore to minimize the cost, she needs to sell 20 units of tacos
<span>b. find the minimum cost.
</span>that can be done by substituting the previous result, 20 tacos, in the original equation:
<span>C(x) = x^2 - 40x + 610
</span>C(20) = (20)^2 - 40(20) + <span>610
</span>= 400 - 800 + 610
= 210
the minimum cost will be 210 dollars
